To celebrate Pi Day this March 14 (or 3/14 or 3.14), we visit the balmy waters of Little Bahama Bank, Bahamas. Two Atlantic spotted dolphins were photographed here blowing a bubble ring, also known as a toroidal ring. And if they were to calculate the circumference of their bubble ring, they’d need to use our favorite irrational number, π.
Happy Pi Day!
